That is, in the connector 1 configured as described above, the fulcrum 35a of the release jig 100 is an opening at the front end portion of each unlocking space portion 35 in the axial direction X, as shown in FIGS. 3 and 7. It is formed on the outer edge of the main body 30 in the above. With this configuration, the connector 1 can properly secure the fulcrum 35a of the release jig 100 when the terminal 2 is released from the lock by the lance portion 33. As a result, the connector 1 and the wire harness WH1 can be made compact by realizing a configuration in which the terminal 2 can be properly released by the lance portion 33, and can suppress the increase in size as described above.
